The books state distances aboard this ship. The drawing has to produce the
same ones or it is wrong — so it is made to, and the working is shown. These
run again on every build; a compartment moved by a metre fails them.

“The galley is forward of the frame, on the port side” The Way Out Closes
Compartment 2-02 spans frames [30,46], band port; the frame annotation is at 62. 46 < 62, so the galley is forward of it and to port. The only fully-stated position in the ship, and the sheet is built outward from it.
-
“The cell is aft of the frame” The Way Out Closes
Compartment 2-06 spans frames [62,78]; the frame is at 62. Aft of it, as stated.
-
“The after ranging board is at the after end of the bay” The Way Out Closes
The after bay 2-08 ends at frame 108; the after ranging board 2-09 begins at 108. Contiguous, and aft of the bay's volume.
-
“The locker run is reached at the frame” The Way Out Closes
Locker run 2-04 ends at frame 56 and the cross-passage 2-05 runs 56–62 to the frame, so a man going past somebody at the frame reaches it in one move.
-
“The run behind the connector passes under the new frame” The Way Out Closes
Compartment 5-02 spans frames [58,68], which brackets the frame at 62. The fault is therefore under the new structure, as the engineer says.

“No frame number is ever quoted FOR THE The Far Roads in 122 chapters” The Way Out Closes through The Last Cache; the single counter-example is The Last Cache, chapter 25
Grep of all 122 chapters returns exactly ONE numbered frame reference: “Frame nine to frame twelve, port side, and it's the plate the family put in her at the shoal” (The Last Cache, chapter 25) — and that is EWART'S hull, not Kestrel. So the franchise does number frames in dialogue when it wants to, and simply never does it for this ship. That is why hull.frames is graded fixed rather than published, and why every position on this sheet is expressed relative to THE frame rather than to a number.
